The Stainless Steel 347 and 347H Seamless Pipes are stabilized with niobium and include elements such as chromium (17–19%), nickel (9–13%), carbon, manganese, silicon, and phosphorus. The addition of niobium boosts their resistance to carbide precipitation and corrosion. These grades showcase a tensile strength of about 515 MPa, yield strength of 205 MPa, and an elongation of 40%. With a higher carbon content, Stainless Steel 347H provides enhanced creep strength and heat resistance, making both alloys ideal for high-temperature applications, along with excellent weldability and toughness.
